M ATTORNEY United States Patent 3,350,781 CARD INDEXING PUNCH Arthur V.Bender, 29 Woodland Road, Maplewood, NJ. 07040 Filed lIuly 8, 1966, Ser.No. 563,883 2 Claims. (Cl. 30-358) ABSTRACT OF THE DISCLOSURE A punchhas a Ist jaw carrying a punching pin that is coactive with a dieopening in a at face of a second jaw, and a gauge formed of sheet metalhas a main dat portion set on said ilat face of the second jaw andformed with a gauge edge extending upwardly from said flat face intransverse relation to the second jaw, said main portion also having anarm formed with a gauging edge in angular relation to thefirst-mentioned gauging edge so that said edges are adapted to beabutted by two meeting edges of a card to be punched and thefirst-mentioned edge has a notch to provide clearance for said punchingpin.

This inventionrelates in general to a punch for indexing cards, forexample, photograph slides which comprise transparencies mounted incardboard frames; and a primary object of the invention is to provide anattachment for a punch, particularly a hand punch, whereby a card like aphotograph slide may be accurately positioned with each of two angularlyrelated sides in a predetermined relation to the punching elements suchas a punch pin and a cooperative die.

The invention is especially useful for producing a notch in an edge of aslide in a predetermined relation to an angularly related edge of theslide so that the slide may be easily and accurately oriented in a slideprojector, the notch and its relation to the second-mentioned edge ofthe slide indicating by sight or touch the proper positioning of a slidein a projector.

Another object of the invention is to provide a novel and improvedconstruction and combination of a hand punch and a gauge by which theproper positioning of the card or slide holder relative to the punch canbe easily and quickly effected.

A further object is to provide a novel and improved gauge attachmentthat can be easily applied to and removed from a punch and which shallbe simple and inexpensive in construction.

Other objects, advantages and results of the invention will be broughtout by the following description in conjunction with the followingdrawings in which:

FIGURE 1 is a side elevation of one type of punch and a gauge attachmenttherefor according to one embodiment of the invention;

FIGURE 2 is an enlarged fragmentary central longitud* inal sectionalview through the jaws, the punching elements and the gauge attachment;

FIGURE 3 is a fragmentary horizontal sectional view approximately on theplane of line 3-3 of FIGURE 2;

FIGURE 4 is a fragmentary side elevation of the side of the punch jawsand the gauge attachment opposite that shown in FIGURE 1;

FIGURE 5 is a perspective View of a photograph slide that has beennotched or indexed by the punch, and

FIGURE 6 is an enlarged perspective view of the gauge attachment.

For the purpose of illustrating the principles of the invention, I haveshown in the drawings a known type of hand punch which includes a bodyportion A having a hand grip 1 extending therefrom, the body portionbeing formed to provide the jaws 2 and 3 which are separated by a slot 4into which is inserted the card, sheet or photoice l graph slide to -bepunched. The jaws 2 and 3, respectively, carry the punching elements,that is the punching pin 5 and the die 6. The punching pin is actuatedby lever 7 having the grip portion 8 and pivotally secured to the bodyportion by the pivot pin 9. The lever 7 is associated with the punchingpin 5 so as to actuate the pin and cause it to be brought intocooperative relation with the die 6, to punch the card. An expansionspring ll0 is arranged between the grip portions 1 and 8 so that thegrip portions will be urged normally into an extended position with thepunching pin in spaced relation to the die as best shown in FIGURES 1and 2. Obviously, the punch pin may have other shapes than cylindricalas shown.

The jaw 3 has a plate portion 11 formed with a llat face ush with theedges of the opening 6a through the die 6, and the jaw 4 has a plateportion 12 formed with a at face in opposed relation to the face of theplate 11 and through an opening in which `reciprocates the punching pinS. The faces of the plate portions 11 and 12 ofthe jaw are spaced aparta distance slightly greater than thickness of the card or photographslide to be punched, and in accordance with the invention a gauge B isinterposed between the plate portions '11 and 12 of the Jaws.

The guage is shown as comprising a piece of sheet metal having a flatmain portion 13 to lie llatwise upon the face of the plate portion 11 ofthe jaw 3 and formed with opposed parallel ilanges 14 one to abuttinglyengage each of opposite sides of the jaw 3. In other Words, the anges 14are spaced apart a distance approximately equal to the width of the jaw3. The gauge is separably secured to the jaw in any suitable manner,preferably by screws 15 that pass through openings 16 in the anges 14and are screwed into complementarily threaded holes in the jaw. Thegauge has one gauging edge 17 that is disposed transversely of the jaw 3and in chordal or transverse relation to the opening 6a of the die asbest shown in FIGURE 3, and said edge has a notch 18 therein that ispreferably arcuate and approximately concentric with the die opening 6a.However, the notch may be of different shape and size, its primarypurpose being to provide clearance for the punching pin. The gaugingedge 17 is adapted to be abutted by one edge 19 of a photograph slide 1Cthat is to be notched, and the gauge has another gauging edge 20 to beabutted by an edge 21 of the photograph slide that is angularly relatedto the side 19 in the present instance at a 90 angle, these gaugingedges serve to locate the slide edges 19 and 20 in proper relation tothe die opening. The gauging edge 20 is formed on a lateral andforwardly extending arm 21 of the main portion 13 with said edge 20 inthe present instance spaced from the corresponding side of the jaw 3 anddisposed approximately parallel thereto.

With this construction, when it is desired to notch a photograph slide,the slide is viewed by the operator and the two angularly related edgesthat are to be used for orienting the slide in a projector aredetermined, after which the slide is inserted in the slot 4 between thejaws 2 and 3 with one edge, in the present instance the edge 19 abuttingthe gauging edge 17 of the gauge and with the other edge of the slide,in the present instance the edge 21 abutting the gauging edge 20,whereupon the grip portions 1 and 8 of the punch are squeezed in theusual way to force the punching pin 5 into cutting relation to the die,as a result of which a notch 23 is formed in the edge of the slide thatoverlies the die opening.

It will be understood by those skilled in the art that the gauge may beadjustably mounted on the jaw 3 and the depth of the notch 23 in theslide can be varied by changing the chordal relation of the gauging edge17 to the die opening, and similarly the position of the notch withrespect to the edge 21 may be varied by changing the distance of thegauging edge 20 from the die opening.

Other modications and changes in the structural details of the punch andthe gauge may be made within the spirit and scope of the invention asdefined in the appended claims.

I claim:
